The Astronomy Center has provided educational resources to introductory astronomy educators since 2003. Over the past 20 years, the rapid pace of discovery has rendered some of our linked resources obsolete. Thus, the Astronomy Center will be decommissioned on March 1, 2022. Our highest quality resources will be retained on ComPADRE.org.
This web site contains lecture notes for an introductory course on galaxies and cosmology. It is meant for a non-science audience with a limited background in trig and algebra.
